[0027] Please refer to the accompanying Figure 1 to the accompanying Figure 5 The utility model provides a new born baby aspirator soundproof cover, including:
[0028] The top of the upper protective cover 1 is fixedly provided with a protective cover handle 11, and the top of the upper protective cover 1 is provided with an aspiration pipe mounting hole, a sealing plug 4 is mounted above the aspiration pipe mounting hole, the bottom of the upper protective cover 1 is fixedly provided with a magnetic buckle 3, the top of the upper protective cover 1 is fixedly provided with a protective cover handle 11, and the top of the upper protective cover 1 is provided with an aspiration pipe mounting hole, a sealing plug 4 is mounted above the aspiration pipe mounting hole, the surface of the sealing plug 4 is fixedly connected with an extension sleeve 41, the extension sleeve 41 is inserted into the inside of the aspiration pipe mounting hole, and a mounting opening 42 is formed in one side of the sealing plug 4, the mounting opening 42 is used to set the sealing plug 4 on the aspiration pipe, the bottom of the upper protective cover 1 is fixedly provided with a magnetic buckle 3, the bottom of the upper protective cover 1 is fixedly connected with a silica gel sealing ring 12, the silica gel sealing ring 12 is attached to the inner wall of the upper protective cover 1, and the bottom of the lower protective cover 2 extends to the outside of the upper protective cover 1;
[0029] The lower protective cover 2 is arranged below the upper protective cover 1, the top of the lower protective cover 2 is fixedly provided with a magnetic buckle 3 corresponding to the bottom of the upper protective cover 1, the lower protective cover 2 and the upper protective cover 1 are both composed of a shell 5, a middle layer filling 6 and an inner lining 7, the inner lining 7 is arranged on the inner side of the shell 5, the inner wall of the shell 5 is designed in a honeycomb shape, the middle layer filling 6 is arranged between the shell 5 and the inner lining 7, the inside of the lower protective cover 2 is placed with an aspirator main body 10, and the surface of the lower protective cover 2 is mounted with a filter screen 8, the filter screen 8 is provided with two groups, the two groups of filter screens 8 are arranged in front of and behind the lower protective cover 2 respectively, and the filter screen 8 is designed as double layers.
[0030] The ventilation pipe 9 is arranged in the inside of the lower protective cover 2, and the ventilation pipe 9 is designed as a multiple "S" shape elbow pipe, and the ventilation pipe 9 is used to connect the lower protective cover 2 and the filter screen 8.
[0031] This utility model proposes a noise-reducing protective cover for a newborn suction device. In use, the suction device body 10 is placed inside the lower protective cover 2. Then, the sealing plug 4 and the extension sleeve 41 are fitted onto the suction tube through the installation opening 42. The suction tube is inserted into the upper protective cover 1, and the extension sleeve 41 is inserted into the suction tube installation hole. Then, the suction tube is connected to the suction device body 10. The power of the suction device body 10 is turned on and the pressure is set. The upper protective cover 1 is placed on top of the lower protective cover 2, so that the bottom of the silicone sealing ring 12 is inserted into the lower protective cover 2. At this time, the magnetic buckle 3 at the bottom of the upper protective cover 1 and the magnetic buckle 3 at the top of the lower protective cover 2 attract each other, so that the upper protective cover 1 and the lower protective cover 2 are aligned, thereby covering the outside of the suction device body 10.

It uses the porous structure to convert sound energy into heat energy and specifically absorbs low- and medium-frequency motor noise. The inner lining 7 is made of medical-grade butyl rubber, which uses high-density damping characteristics to reduce sound wave transmission. According to third-party testing (based on GB / T 3767), the operating noise of the equipment has been reduced from the original 72dB(A) to 52dB(A).
[0033] By using a three-layer noise reduction system, noise of different frequencies is weakened, thereby reducing the impact of noise generated by the suction device on people during operation, while avoiding excessive noise that may cause anxiety in patients.

This allows the protective cover to dissipate heat through the filter screen 8 and the ventilation pipe 9 while silencing the sound, thus preventing the suction device from stopping or being damaged due to overheating during use.
[0035] As a further improvement of this utility model, the filter screen 8 is set to be double-layered and detachable, with the outer layer being a nylon dustproof mesh and the inner layer being a HEPA filter paper, which facilitates cleaning and replacement during use.
[0036] As a further improvement of this utility model, by adding a nano-silver coating to all contact layer materials of the protective cover, the antibacterial properties of the protective cover can be effectively improved.
[0037] As further improvement of the utility model, through setting up magnetic attraction buckle 3, make upper protective cover 1 and lower protective cover 2 through magnetic attraction buckle 3 and carry out quick dismounting, make in emergency situation can quickly dismount protective cover, has improved its practicality.
